Glad I found this thread. I will be getting my TF-100 next season as our pool has cost more than our budget for the year and I can't afford it. I'm also color blind and was really worried about what color each test would result in. I've been using Test strips (I KNOW...I KNOW...BOO on test strips...But I already have them and am out of money... 
)and having to take pictures to show my wife for some of the trickier comparisons. Good to know that I'll most likely be fine with the TF-100. Excited for next season!
